Write or select an algebraic expression that represents a real-world situation.

Clarifications:

Essential Understandings

Concrete:

  • Use manipulatives to represent a situation (i.e., John has five apples and he gives some to Jim = 5 – x).
Representation:
  • When given a verbal expression (i.e., eight plus y), students must select the appropriate algebraic expression (8 + y).

Number: MAFS.6.EE.1.AP.2a Category: Access Points
Date Adopted or Revised: 06/14 Cluster: Apply and extend previous understandings of arithmetic to algebraic expressions. (Major Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Name Description
MAFS.6.EE.1.2: Write, read, and evaluate expressions in which letters stand for numbers.
  1. Write expressions that record operations with numbers and with letters standing for numbers. For example, express the calculation “Subtract y from 5” as 5 – y.
  2. Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. For example, describe the expression 2 (8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms.
  3. Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). For example, use the formulas V = s³ and A = 6 s² to find the volume and surface area of a cube with sides of length s = 1/2.
